Sit in the machine with your back against the backrest and your shoulder blades pressed back.
Place the feet flat and straight on the rungs or ankle supports of the machine, and the outside of your knees resting against the leg pads.
Begin exercise with the legs close together.
Execution:
In a smooth and controlled motion, while contacting the hip abductors, spread you legs as far apart as possible - keeping the pelvic and back positioned against the backrest.
Pause briefly, then slowly return the legs to the original position, without letting the weight completely touchdown on the weight stack. Repeat.
Training Tips:
Keep shoulders back and your back pressed firmly against the backrest of the machine. (note: if your back does not touch backrest, place extra pads behind you)
While performing your reps always keep the weight slightly suspended from the stack.
Refrain from twisting or turning your legs or feet during the exercise.
